The walker... This thing will be made in limited supplies. It will be perfected made even better...it is your terminator. But pricey and not as generalized as the big dog The big dog can carry more, it will come in variety. it will be long range launchers and short range cougars eviscerators. They can carry supplies too like food or reload ammo. They will be cheaper and they will be the grunts of death. And the following This is your new cop... your new law enforcement tool. Put a high power burning laser on it that has a the intensity to vaporize metal and even if it is only two seconds... it could kill people or destroy tanks. It's like star wars but scarier and less fun.
